Problems solved by technology

However, in many scenarios, the background of the text image may be complex (such as insufficient image brightness, image blur), if the traditional AdvancedEast algorithm is used to extract the text area from the image, the effect at the beginning and end of the text area is not good, resulting in text area inaccurate

Abstract

The invention relates to a method and device for extracting a text region from an image, computer equipment and a storage medium. The method comprises the following steps: acquiring an image containing a text area; after feature extraction processing of layer-by-layer convolution is carried out on the image, enhancement processing is carried out on features corresponding to the text area, and a corresponding first enhancement feature is obtained; after layer-by-layer deconvolution feature reduction processing is carried out on the first enhanced feature, enhancement processing is carried out on a feature corresponding to the text region to obtain a corresponding second enhanced feature; fusing the first enhanced features and the second enhanced features at the same level to obtain fused features; and extracting the text region from the image according to the fusion features. By adopting the method, the accuracy of the text area can be improved.

Description

technical field [0001] The present application relates to the technical field of text image recognition, and in particular, to a method, apparatus, computer device and storage medium for extracting text regions from an image. Background technique [0002] Text image recognition technology is a technology to obtain computer-recognizable text from text images. Text image recognition technology mainly includes two stages: extracting text regions from text images and recognizing the extracted text regions to obtain computer-recognizable text. The accuracy of the text area has a great influence on the accuracy of the recognized text. However, in many scenarios, the background of the text image may be complex (such as insufficient brightness of the image, blurred image), if the traditional AdvancedEast algorithm is used to extract the text area from the image, the effect of the first and last parts of the text area is not good, resulting in text Region is not accurate.
